1 oz Gold Bars

One-ounce gold bars are the most widely traded weight in the gold bar market, offering a full troy ounce of gold in a compact, rectangular form. Nearly all 1 oz gold bars are struck or cast to a fineness of .9999 (24-karat), and each bar carries an engraved or stamped face that displays the weight, fineness, refiner's hallmark, and a unique serial number. Most are sealed at the mint in a tamper-evident assay card that also contains a matching certificate of authenticity.

The category spans output from some of the world's most recognized refineries. PAMP Suisse is perhaps the best-known name in the segment — their Lady Fortuna design, featuring the Roman goddess of fortune in relief, has been produced in Geneva since 1979 and is among the most recognized bar designs globally. The Perth Mint (Australia), Valcambi (Switzerland), Credit Suisse (Switzerland), and the Royal Canadian Mint each produce 1 oz bars with their own distinctive hallmarks and packaging, all meeting the same .9999 fine standard. The assay card format common to this weight makes these bars straightforward to store, transfer, and account for in a collection or holdings.

At Lone Star Coins, this collection includes 1 oz gold bars from PAMP Suisse, Perth Mint, Valcambi, Credit Suisse, and the Royal Canadian Mint, as well as our-choice assay bars when specific refiner preference is flexible. Pricing is tied to the live gold spot market and updated in real time. All bars are in stock at our San Antonio showroom and available to ship nationwide or pick up in person.
